Analisis Efektivitas Laju Perpindahan Panas Alat Penukar Kalor Tipe Shell And Tube

Abstract

The development of the process industry in a production requires equipment that has high efficiency so that the energy used can be utilized optimally, this is closely related to the existence of science to be able to measure the effectiveness of heat transfer in heat exchangers, especially shell and tube types. Study of the effectiveness of a heat exchanger is needed to increase the effectiveness of the heat exchanger, because each heat exchanger product created has different effectiveness. This study aims to calculate the effectiveness of heat transfer in a shell and tube type heat exchanger and analyze the effect of flow rate and inlet temperature on the effectiveness of heat transfer in a shell and tube type heat exchanger. The method used in this study is an experimental method, namely conducting direct experiments using experimental tools to obtain the necessary data. With a shell and tube type heat exchanger design that can vary the flow rate of the incoming hot fluid, experimental data will be recorded in the form of the incoming and outgoing temperatures of the hot fluid and cold fluid, the flow rate of the hot fluid and cold fluid. From the test results of the shell and tube type heat exchanger with the three hot fluid temperatures, namely 40 º, 50 º, and 60 º, the temperature with the number 40 º C is the temperature that produces the highest effectiveness value, namely: at a flow rate of 1 liter/minute = 22.73 %. It was also found that the higher the value of the hot fluid flow rate, the lower the effectiveness of the heat transfer rate that occurs in the shell and tube type heat exchanger.
